The Acta Group, L.L.C.'s (Acta) thoughts are below on what may be headed our way in 2011 from the U.S. Environmental Protection Agency's (EPA) Office of Chemical Safety and Pollution Prevention (OCSPP). In short, the general trends established by the Obama Administration during the past two years are expected to continue notwithstanding the 2010 election results. At the same time, the impact of ...

Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions. EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...

Problems with reducing nitrogen oxides (NOx) are widespread in the general process industries. These industries, together with medium size utility and power generators contribute about 15 percent of global NOx emissions. The emission sources addressed include various heaters employed in chemical and petrochemical plants, nitric and sulfuric acid plants, glass furnaces, iron and steel mills, ...

ABSTRACTLong overlooked, the air emissions associated with biological treatment of process wastewaters continue to be further scrutinized and regulated. The common approach is to utilize EPA’s Water9 as a model to present findings and support permitting activities. It is essential when using a model that not only is the facility modeled appropriately, but also that the specific compound ...

Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

As part of an ongoing objective to reduce emissions and conserve energy at the Ford Motor Company’s Dunton Technical Centre, Maxsys Fuel Systems have been fitted to the boiler plant, helping the company to achieve over 5% reduction in gas usage with a commensurate reduction in emissions. The Energy Committee at Dunton decided to investigate ways of reducing gas usage by improving ...

ABSTRACTThe Des Moines Wastewater Reclamation Authority operates a 97-million gallon per day regional wastewater reclamation facility (WRF) largely constructed in the mid 1980s to serve the greater Des Moines, Iowa metropolitan area. Originally constructed in a largely rural area, current plans for the area around the WRF establish a need for emissions control to reduce offsite odor impacts, in ...

Good Neighbours Limit their Noise Impact Long-term noise monitoring has taken place in various applications for many years. Business such as airports, power stations, refineries, mines, etc., may be required to perform continuous noise monitoring to ensure legal operating conditions are not breached, and to demonstrate to local authorities and communities that the business continues to be a good ...

Chemical Engineering Magazine journalist, Amer Khaqan investigates the installation of a relatively unknown method of emissions monitoring, PEMS (Predictive Emissions Monitoring System) at the methanol production facility of Arrazi in Saudi Arabia. The article shines light on the advancing technology of PEMS and explains the advantages of installing one, over the commonly used CEMS (Continuous ...

The ProblemMandates on the industry to meet certain environmental standards including NOx SIP requirements, combined with corporate responsibility and sustainability programs make the management of Petrochemical Corp's increasingly complex environmental program critical to their continued success. The SolutionImplementation of the VisionMonitor Compliance Intelligence ...

UK Energy and Climate Change secretary said debate on legal structure to replace the Kyoto Protocol was left to next year. Energy and climate change secretary, Chris Huhne, defended his upbeat assessment of the last week’s Cancun agreement, arguing that it was "the most significant package overall since the [1997] Kyoto protocol." Most observers think the Cancún agreement kept the UN ...

Routine operations of a nuclear research reactor and its facilities offer opportunities for collection of rare environmental tracer datasets which can be used for atmospheric dispersion model evaluation studies. The HIFAR reactor near Sydney, Australia, routinely emits the radioactive noble gas 41Ar, and other radionuclides such as 133Xe and 135Xe are also emitted from nearby radiopharmaceutical ...

“The world is facing twin energy-related threats: that of not having adequate and secure supplies of energy at affordable prices and that of environmental harm caused by consuming too much of it.” Daniel Hecker, economist, Bureau of Labor Statistics, July 2005 Buildings in the U.S. consume 72 percent of all electrical energy produced in this country. Emissions associated with ...

Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...

The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...
